In order to stabilize a base line of a differential heat signal in a differential thermobalance and to improve measurement accuracy of differential calorimetry, the present invention provides a protuberance to each of the sample holder and reference holder, detects a signal, which is obtained by subtracting the temperature difference signal between both protuberances from the temperature difference signal between the sample holder and the reference holder, as a differential heat signal and thus reduces any influences of temperature gradient inside a heating furnace and stabilizes the base line of the differential heat signal to improve accuracy of differential calorimetry. |
